Description
About:
- Infinite Liquid Magnesium is a reagent set for determination of magnesium concentration in human serum and plasma based on colorimetric blue method.
- Infinite Liquid Magnesium is a ready-to-use, single liquid reagent system.
- Magnesium can be determined in just 5 minutes at 37°C.
- Infinite Liquid Magnesium is linear upto 5 mg dl.
- Infinite Liquid Magnesium can be used on any Spectrophotometer, Discrete semi automated and Automated analyzers. Programmed can be designed for any specific analyzer upon request.
- There is no significant interference in samples containing upto 50 mg/dl of Bilirubin and upto 39 mg/dl of Ascorbic Acid.
Principle:
Magnesium ions react with xylidyl blue in an alkaline medium to form purple coloured complex. The intensity of the purple color is directly proportional to the concentration of magnesium in the specimen.

Quality Control:
To ensure adequate quality control, it is recommended that each batch should include normal and an abnormal commercial reference control serum. It should be realized that the use of quality control material checks both instrument and reagent functions together. Factors which might affect the performance of this test include proper instrument function, temperature control, cleanliness of glassware and accuracy of pipetting.
- The reagent and standard are ready-to-Use and are stable till expiry whenstored at 2- 8°C.
- Contamination of the reagent should be strictly avoided.
The kit should be stored at 2- 8°C and is stable till the expiry date indicated
